Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Peel, seed, and cube 2 lbs butternut squash and 12 oz sweet potato into 1-inch pieces.
  2. Step 2: Toss the cubed vegetables with 2 tbsp olive oil on a baking sheet, then roast for 25-30 minutes until tender and caramelized at the edges.
  3. Step 3: Heat a large pot over medium heat. Add 1 diced onion and cook for 5 minutes until softened and translucent, stirring occasionally.
  4. Step 4: Stir in 3 minced garlic cloves and cook for 1 minute until fragrant, stirring constantly to prevent burning.
  5. Step 5: Pour in 4 cups vegetable broth and bring to a gentle simmer. Add the roasted vegetables, 1/2 tsp cinnamon, and 1/4 tsp nutmeg. Simmer for 10 minutes to meld flavors.
  6. Step 6: Use an immersion blender to puree the soup until completely smooth (or transfer to a blender in batches).
  7. Step 7: Stir in 1/4 cup heavy cream and simmer for 2 more minutes until heated through.
